COMBINED LOCK AND HASP.

'.EECIPICATION forming part 0f Letters Patent No. 347.695, dated August 17, 1856.

Serial No. 205441. (No model.)

and afterward specifically pointed out in the claims, due reference being had to the accomcompanying drawings, forming part of this specification, wherein- Figure I is a plan view ofmyimproved lock and hasp applied to a cellardoor; Fig. 2, a

longitudinal section partly in elevation; Fig. 3, an end view; Fig. 4, aview ofthe key; Fig. 5, a section on the line .fr-1, Fig. l; Fig. 6, a partial section showing the locking mechanism partially unlocked, and Fig. 7 a partial section showing the same mechanism fully unlocked.

Referring to the drawings, the letter A indicates the hasp secured to the door by a staple,

. c, andprovided at its free end with a barreLB.

C indicates the base-plate ofthe lock secured to the dooljamb and carrying a keeper, D, and the lock-casing E, said keeper and casing being so arranged relatively to each other that the barrel B of the hasp Will lie snugly between thern when in a position to be locked.

F indicates a latch-bolt, (preferably square in crosssection,) which slidesin suitable bearings in the casing, and said latclrbolt, when the hasp is in position to be locked, is pushed through the barrel B of the hasp and into the keeper D, effectually bolting the hasp to the bolt. Y l

G indicates a bolt, which is secured in a suitable bearing in the casing, and is' encircled by a spring, g3, which is secured at one end to the holt and at its other end to the bearing, so that the spring constantly exerts a pressure to force the bolt downward. The latch-bolt F is perforated at j", and when said latch-bolt is iu a position to lock the hasp the bolt G is forced down through said perforation f, and prevents the latch bolt from being retracted. The bolt G is provided at its upper extremity with two arms, g' g2, the arm g' being much the lougerof the two and curved, as clearly shown in Figs. 5, 6, and 7.

H indicates the key having two wards, 71.71,', arranged nearly or at right angles to each other, the ward l1 being longer than the ward h', and both wards being preferablysomewhat curved, as shown in the drawings.

When the latch-bolt F is in a position to lock the hasp, and is itself locked in position by the bolt G, the parts may be unlocked by means of the key H, as follows: The key is inserted in the keyvholet' and turned in the proper direction until the ward h comes in Contact with the under side of the arm g' of the bolt G. and upon continuing to turn the key the bolt G is raised to the position shown in Fig. 6, or about one-halfthe distance necessary to disengage said bolt from the latch-bolt F. At the moment the ward h' passes from underthe arm g theward h. engages the arm g2, and a further rotation of the key raises the bolt G from out the perforation in the latchbolt F, and the saidlatch-bolt may be retracted by means of the knob f2.

In order to prevent the latch-bolt from being entirely withdrawn from the casing, it is provided with a shoulder, f3.

By forming the arms g and g2 of the bolt G as above described, it renders it very difficult, if not impossible, to raise the bolt without the proper key; for should it be attempted to raise said bolt with a key having but one ward such ward would have to be of such length in order to raise the bolt the necessary distance that its end would engage the short arm g'l of the bolt when said bolt is in its lowestposition, and it would merely exert a force in a lateral direction and fail to move the bolt at all, for should it be attempted to raise the bolt with an instruinent having a ward that would clear the arm g2, the ward would become disengaged from the arln g before the bolt had been raised a sufficient distance, and the bolt would iinmediately be forced back `by the action of the spring g.

In order to immediately lock the parts in position, itis only necessary to push the latch bolt F in until it enters the keeper D, when the bolt G will be forced by its spring in the perforation f.

In order to give the bolt G a firm bearing, the base-plate C may have a boss, e, formed upon it with a socket to receive the endof the bolt when the parts are locked.

Having thus described my invention, what I claim is l. In combination with the hasp having a barrel at one end, a keeper, alatch-bolt passing through said barrel and keeper, and a spring-bolt passing through a perforation in said latch-bolt, substantially as described.

2. In combination with the hasp, the latchbolt F and the spring-bolt G, said spring-bolt being provided at one end with the arms ggl, and adapted to enter a perforation in the latchbolt F, substantially as described, and for the purpose specied.

In combination with thehasp, the latchbolt F, the keeper D, and a bolt l'or locking said latch-bolt in position, substantially as shown and described.

4. In combination with the hasp, the keeper D, the perforated 1atch-bolt F, provided with a shoulder, f3, and a bolt, G, adapted to enter the perforation in the latch-bolt and provided with the arms g g2 and springj, substantially as described, and for the purpose specified.

In combination with the hasp, the perforated latch-bolt F, the bolt G, adapted to enter said perforation in the latch-bolt and provided
